Synchronous Optimization for Start/Stop and Yaw of Wind Farm Turbines
In existing wind farms,the overall power output of the wind farm can be increased by yaw controlling.However,the start/stop and yaw cooperative control of the wind turbine is often not considered which does not maximize the power output of the wind farm.A wind farm layout optimized method was proposed considering start/stop and yaw synchronization control based on the improved three-dimensional wake model and yaw flow superposition model.The start/stop state of wind turbines in the wind farm can be controlled by using random number[0,1]distribution.The maximum power output of Chapman Ranch wind farm was took as the objective function,and combines the wind resource data of the wind farm to optimize three wind farm layout models(wind farm start-stop,yaw controlling,start-stop and yaw integrated control)using particle swarm algorithm.According to the results of the study,the power output of the wind farm is increased by 11.9％considering yaw controlling.However,the power output of the wind farm can be increased by 17.7％with start-stop and yaw integrated optimized.This study is an important guidance for how to improve the overall power output of existing wind farms.
